Developing a Virtual Reality Simulation System for Preoperative Planning of Robotic-Assisted Thoracic Surgery

Area of Science:

• Thoracic surgery
• Medical simulation
• Virtual reality applications

Background:

• Robotic-assisted thoracic surgery (RATS) is standard for lung cancer but presents challenges in visualization and tactile feedback.
• Minimally invasive approaches in RATS require enhanced navigation through complex pulmonary anatomy.
• A virtual reality (VR) surgical navigation system was developed to address these challenges.

Purpose of the Study:

• To enhance preoperative familiarization with patient-specific anatomy for RATS.
• To improve preoperative simulation and intraoperative navigation in thoracic procedures.
• To optimize surgical planning and execution in lung cancer treatment.

Main Methods:

• Integration of 3D CT scan data into Perspectus VR Education software.
• Utilization of head-mounted displays (HMDs) for interactive 3D reconstruction of pulmonary structures.
• Real-time intraoperative guidance using 3D images displayed via Tile-Pro™ multi-display during RATS.

Main Results:

• Precise visualization of pulmonary structures and lesion relationships was achieved.
• Enhanced surgical safety and accuracy were demonstrated.
• True 3D interaction with patient data facilitated effective surgical planning.

Conclusions:

• VR simulation with HMDs provides a novel method for developing robotic surgical skills.
• Integration with routine imaging improves preoperative planning, safety, and accuracy in anatomical resections.
• This technology aids lesion identification in RATS, optimizing surgical outcomes.
